Nullification, in United States constitutional history, is a legal theory that a state has the right to nullify, or invalidate, any federal law which that state has deemed unconstitutional. The theory of nullification has never been legally upheld by federal courts. The theory of nullification is based on a view that the States formed the Union by an agreement (or "compact") among the States, and that as creators of the federal government, the States have the final authority to determine the limits of the power of that government. Under this, the compact theory, the States and not the federal courts are the ultimate interpreters of the extent of the federal government's power. Under this theory, the States therefore may reject, or nullify, federal laws that the States believe are beyond the federal government's constitutional powers. The related idea of interposition is a theory that a state has the right and the duty to "interpose" itself when the federal government enacts laws that the state believes to be unconstitutional. Thomas Jefferson and James Madison set forth the theories of nullification and interposition in the Kentucky and Virginia Resolutions in 1798.
